ATTORNEY Patented July 14, 1931 UNITED STATES EDWARD CARTER, OF VANCOUVER, BRITISH COLUMBIA, CANADA TURNHEAD FOR nocK sron'rs Application filed. February 19, 1929. Serial No. 341,222

My invention relates to improvements in turnheads'for dock-spouts and the object of my invention is to provide a turnhead or turnhead joint or junction between two spout sections or between any two portions of spouts which are inclined at the same or similar angle which will permit angular adjustment between the sections of the spout in a horizontal plane but will notrequir'e any change in the vertical inclination of the flowing grain to accomplish this adjustment, the result being that the said turnhead will otter the least possible resistance to the flow of material therethrough, boiling of the grain in the turnhead willbe prevented and a maximum velocity of the material will be attained and maintained.

Other objects are to provide a turnhead which is simple and durable in construction, efiicient in operation, not expensive to manufacture, capable of excluding snow and water and capable of withstanding all stresses which may be communicated to it through the attached spout sections.

Further and more specific objects will be apparent from the following I description taken in connection with the accompanying drawings.

In the drawings Figure 1 is a side elevation of a turnhead constructed-in accordance with my invention showing the same connected to an upper spout section, the lower spout section and turnhead support being omitted.

' Fig. 2 is a vertical mid-section through the turnhead and associated spouts and supporting parts. a I

Fig. 3 is a detached plan View of the turnhead with all other parts removed.

Fig. 4 is a rear elevation of the two cooperating parts of the turnhead showing the upper part raised ofi of the lower part a short distance. I

Fig. 5 is a sectional view through the turnhead substantially on broken line 5-5 of Fig. 3, showing the upper part raised a short distance above the lower part.

Fig. 6 is a cross section substantially on broken line 6-6 of Fig. 2 showing the rectangular shape of a part of the turnhead and lower spout section.

'lower end inserted into the upper turnhead Referring to the drawings, throughout Which like reference'numerals designate like parts, I show a turnhead formed of an upper portion 8 and a lower portion 9. The upper p portion 8 has a rectangular top opening 10 surrounded on three sides by a horizontal flange 11 and provided on the rear or fourth side with a downwardly inclined'flange 12. An upper inclined spout section '13 has its portion 8 and is secured to the horizontal flanges 11 'by angle bars 14 andan angle plate 15 and to the'inclined flange 12 by an angle bar '16,suitable bolts or rivets 17 being used as securing means. Atthe bottom end, the upper turnhead portion 8 has a circular, horizontal extension 18 provided with a downwardly extendingflange ltl which is adapted to fit over a cylindrical neck 20 on the lower turnhead portion 9, to thereby'form a swivel joint between saidtwo parts. The neck 20 on the lower section is connected with an inclined rectangular portion 21 which 'is adapted to have a lower spout section 22 securedthereto. The passageway at 21 in the lower section 9 and the corresponding passageway in the upper section 8 are substantially in alignmentwith each other and with the two spout sections when the turnhead is assembled and all of said parts are in the same vertical plane, and the opening at the interfitting flange 19 and neck 20 is relatively large in diameter so that the material flowing downwardly through the spouts will not be forced to change its vertical inclination in such a manner as to retard its velocity'or to produce boiling, in passing from the upper to the lower spout section. For this reason I am able touse spout sections of less incline be yond the turnhead than would be possible if the turnhead retarded the velocity of the material. The pivot joint formed at the'interfitting flange 19 and neck 20 is me. substan-' tially horizontal plane which intersects the spout sections at an angle, thus forming an elongated opening in the general direction of the spout sections. Toallow relative swinging movement of the two turnhead members and still maintain complete registration of the openings and allow ample clearance for the grain when the turnhead sections are turned at an angle, it is necessary to make the diameter of the pivotal joint at least as great as the maximum dimension of the opening in the plane in which the pivotal joint intersects the inclined spout.

The lower turnhead section 9 has a hub 23 on its bottom and said hub 23 is provided with a vertical pivot pin 24 which has a bearing in a block 25 and cross bar 26. The cross bar 26 is secured to bracket arms 27 which are rigid with a vertical support 28, which support also carries the upper spout section 13.

The upper spout section 13 and the upper portion 8 of the turnhead are rigidly mounted on the support 28 while the lower turnhead portion 9 is rotatably supported on the pivot pin 24 and may be turned sidewise in either direction to allow for horizontal adjustment of the lower spout sections. When the lower turnhead sections 9 is turned to either side of the position shown in Fig. 3, the path of ma terial which is flowing therethrough will obviously be deflected or changed in a sidewise direction but the angle of descent will not be changed and the velocity of the material will not be appreciably lessened within the ordinary limits of adjustment of the turnhead. The path of this material is shown by dotted lines Pin Fig. 2. 7

It will be noted that the interfitting ends 19 and20 of the two turnheadportions are substantially horizontal while the pivot pin 24 is vertical and the passageway for material through the horizontal ends 19 and 20 is straight and is inclined sharply from either the vertical or horizontal to meet the requirements of the material the spout is de signed to handle. 7

By fitting the flange 19 over the outside of the neck portion 20, a substantially water tight joint is formed.

The foregoing description andaccompanying drawings clearly disclose a preferred embodiment of my invention but it will be ob; vious that this disclosure is merely illustrative and that changesin the device may be made within the scope and spirit of the following claims.

VVhat I claim is v 1 1. A turnhead for a spout, embodying two hollow turnhead members 'disposedin substantially the same inclined plane and 'each having oblique ends arranged to register with each other whereby a substantially straight unobstructed passageway may be formed through said turnhead members, said oblique ends being of larger cross sectional area than the spout sections which they pivotally connect.

2. A turnhead of the class described, embodying two hollow turnhead members 'hav'- ing their body portions disposed in substantiallythe same inclined plane and each having an open end formedat an incline relative to its body portion and in alignment with the opening in said body portion the area of said open ends being larger than the cross sectional area of said body portions and means for mounting said turnhead members for relative rotation with their open ends in registration with each other.

3. A turnhead of the class described, embodying a fixedly mounted upper turnhead member having an inclined passageway and having a horizontal opening at its lower end aligned with said inclined passageway and a lower turnhead member rotatable on a vertical axis and having an inclined passageway and provided with a horizontal upper end havingan opening registering with the opening in the lower end-of said upper turnhead member and aligned with said inclined passageway, said horizontal openings being larger than the cross sectional area of the V passageways with which they are connected.

4-. A turnhead of the class described, embodying a fixedly mounted upper turnhead member having an inclined passageway which terminates in a. downwardly directed circular opening of larger cross? sectional area than the passageway disposed in a substantially horizontal plane, a lower turnhead member having an inclined passageway terniinatin at the no )er end in an 11 owardl directed circular opening of larger cross sectional area than the passageway disposed in a substantially horizontal plane and registering with the opening in said upper turnhead member, said openings and'said inclined passageways all being in substantial alignment when said two twinhead members are in the same vertical plane, and pivot means coaxial with said openings and rotatably supporting said lower turnhead member.

5. The apparatus as claimed in claim at in which'said two turnhead members are provided with interfitting annular telescopic portions around said openings.

6. The apparatus as claimed in claim 4 in which the lower turnhead member has an upwardly directed cylindrical neck portion around said opening and the upper turnhead member has adownwardly desired annular flange which fits over said neck portion.

7. The apparatus as claimed in claim 4 in which the two turnhead members are connected respectively with spout sections arranged in alignment with the inclined passageways in the turnhead members.

In testimony whereof I aflix my signature.
